The Milwaukee Brewers announced Zack Greinke won't start Wednesday's game as scheduled but did not offer additional explanation. FOX Sports reported general manager Doug Melvin denied a trade was in the works and said Greinke was "recharging his batteries."
Greinke has yielded 14 runs in 14 innings this month.
He was scheduled to start Wednesday against the St. Louis Cardinals.
Greinke can become a free agent at the end of the season and has reportedly spurned the team's overtures to extend his deal, including an offer similar to the five-year, $100 million contract proposal made to CC Sabathia in 2008.
Sabathia left that offseason in free agency, signing an eight-year, $161 million deal with the Yankees.
Greinke is coveted by multiple teams. As many as eight teams are thought to have bid for Greinke, including the Texas Rangers, Detroit Tigers and Anaheim Angels.
--The Red Sox activated left fielder Carl Crawford from the 60-day disabled list and penciled him into the second spot in the batting order Monday against the White Sox.
Crawford said he'll likely need ligament replacement surgery in his left elbow and might be used at designated hitter more regularly to prevent overtaxing his arm with throws from the shallow Fenway Park outfield.
Crawford hasn't played in the first 89 games this season for the Red Sox. He signed a seven-year, $142 million contract in December 2010 but hit .255 with 11 home runs and 18 steals last season.
Utility infielder Brent Lillibridge was designated for assignment. Lillibridge was acquired from the White Sox in the Kevin Youkilis trade last month.
---Alex Rodriguez of the Yankees had a stiff neck during batting practice on Monday and was moved to designated hitter in the Yankees' lineup. He had been scheduled to start at third base.
---Yankees closer Mariano Rivera, who is out for the season with a knee injury, will ring the opening bell at the New York Stock Exchange on Wednesday.
